T 0 all whom it may concern:

Be it known that I, LOUIS M. BROWN, a citizen of the United States,residing. .at- Beverly, in the county of Essex and State ofMassachusetts, have invented certain Improvements in' Lasting-Machines,of which the following description, in connection with the accompanyingdrawings, isa specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to lasting machines, being herein shown asembodied in the end lasting mechanism of a machine of the bed type andits object is to improve wiper mechanisms of the kind'used in suchmachines.

A particular object; of the invention is to obtain a more effectivebearing of the wiper upon the marginal portion of the shoe bottom forforming the upper upon the feather of the innersole and into the anglebetween the feather and the lip or shoulder It is very desirable thatthe upper be laid flatly down upon the feather from its edge to theshoulder to form a proper seat for the welt and it is also importantthat the upper be firmly pressed down into the angle, instead ofbridging over the angle as it tends to do. One reason for this is foundin the need for providing a seat or bearing for the binding wire withwhich it is customary to secure the upper in lasted position about thetoe and another reason is found in the need for forming the upper down,against theba'se of the lip or shoulder of the innersole so that it canbe sewed closeto said base and form a tight seam which is low enoughdown to allow the surplus upper stock at the inseam to be trimmed closeto the face of the sole and require a minimum of filling material in themiddle of the sole.

I With the above-mentioned'and other obj ects in view a feature ofthisinvention consists in forming the end lasting wipers and theirholders relatively to cause the wipers to have a local or heavy bearinguponthe upper at the inner edge of that marginal portion of theshoebottom which they overlie. This result may be obtained in numerousways of which several are herein explained.

One novel construction embodying this invention includes wiper holdersprovided with wiper seats that are inclined so as to pitch the wipersdownwardly toward the plane of the shoe bottomand in the generaldirection of their advance movement. Herein the wipers, which advanceand close toward each other in the well known manner, are pitched towardeach other by the formation of their seats in the wiper holders. Ofcourse the wipers. might have their bodies, or the portions which arereceived in the seats of the holders, so formed as to give pitch to theupper engaging portions of the w pers.

One important advantage for this embodiment of the .invention appears inthe use of reversible wipers. Such wipers are mounted one side upward intheir holders for a right shoe and the opposite side upward for a leftshoe. It is customary to form wipers with a bevel to produce a thinedge. Reversible wipers of course have to be beveled on both sides. Adifficulty which has been experienced heretofore has been that thebevels gave to the undersides of reversible wipers an undesirable upwardpitch which caused them to bear with greatest force upon the outer edgeinstead of upon the inner edge of the marginal portion of the shoebottom which they overlie. In accordance with this invention the seatsin the holders for such reversible wipers are inclined to balance andpreferably to overbalance the bevels at the edges of the wipers. By sodoing the objectionable upward pitch is overcome and instead there maybe obtained the downward pitch which is desirable-for the reasons abovestated.

It is of course obvious that the wipers, or the portions thereof whichfit into the seats in the holders, may be given the required formationto secure downward pitch of their upper engaging portions, insteadof-changing theusual formation of the wiper seats in the holders. Aspecial construction of toe Wipers embodying this invention andaffording certain advantages is herein shown as obtained by providing abead or. rib-on the acting face of the .wiper at'its.

feather and the lip of the innersole and, if desired, to form a seat orcrease for the toe binding wire.

Advantage'ously the wiper holder may be undercut to present a lip 14 atthe. lower edge of the wiper seat and the wiper will be formed to besupported by said lip, as for example, wit-h a counterpart groove ordepression 16 in its back edge to receive said lip.- By the use of thisformation of holder and wiper the wiper can be held in place by a singleclamp with greater firmness than when the holder and wiper have simplysquared abutting faces.

These and other features of this invention, including certain details ofconstruction and combinations of parts, will be now particularlydescribed and others pointed out in the claims.

Figure l is a perspective view of a toe lasting mechanism of a wellknown commercial form of lasting machine, the two i 1w1per seats in theholders extend oblique I with relation to the median line of the shoeiso that by the inclined walls of the seats Zthe wipers are pitchedobliquely downgwardly and inwardly toward the end and respective sidesof the last.

wiper plates being separated to disclose their shape in end view. Fig. 2isa side elevation of a wiper holder, wiper and clamp. Fig. 3 is a planview showing one modern style of last requiring dissimilar or reverselyshaped wipers for the right and left shoe. Figs. 4: and 5 showmodifications. Fig. 6 is a detail similar to Fig. 2, but on a slightlylarger scale to show clearly the undercut lip at the lower edge of thewiper seat and the cooperating groove in the wiper.

The wiper holders 2 are slidingly mounted in the carriage 4 in whichthey are fitted between supporting and covering plates to be advancedand simultaneously closed inwardly to move the wipers 5 over the lastbottom to the positions indicated in Figs.

2, 3, 4 and 5. This actuation is effected by connections from the wiperholders to the hand lever 6 and by the studs and cam slots shown in Fig.3. The supporting and cover plates are carried by a lasting head 1 whichis vertically movable by a rod connection with a double-ended treadle,not shown, by which the wipers can be raised and depressed independentlyof or simultaneously with their advance and retraction by the hand lever6. The wiper holders are cut away on their under sides to form seats toreceive the wipers. These seats are formed in accordance with thisembodiment of this.

invention with upper walls that are inclined to the plane in which theholders move, which plane, by suitable adjustments familiar to thoseacquainted with this type of machine, is made to be substantiallyparallel with the plane of the shoe bottom which is supported by meansthat includes the usual toe rest 8. This inclination of the upper wallof the wiper seat in the holder will be sufiicient to give to the loweracting face of the wiper a slight pitch downwardly toward the plane ofthe feather of the innersole and the marginal portion of the shoe bottomupon which it is required to press in molding the shoe upper into lastedposition over the feather. By this arrangement the pressure applieddownwardly by the edge of the wiper is localized and the wiper is causedto crowd the upper harder down upon the innersole as it rubs over it andto apply local downward pressure adjacent to the angle between thefeather and the lip or shoulder of the innersole. In Figs. 1, 2 and 8 areversible wiper beveled on both sides is shown. In Fig. 4

It is to be noted from Fig. 2 that the The rear end or wall of the wiperseat in the holder is preferably undercut, for example as shown at 10 inFig. 2, to provide a lip extending under the wiper. to some degree andafforda ing a support which aids the clamp 12 to secure the wiperrigidly in the holder and prevents any loose or tilting movement of thewlper under the wiping and compressing strains to which it is subjectedin operatlon. The reversible wiper is formed with a groove or depressionas shown in said figure of the drawings to fit said lip when the wiperis in the position shown in said figure or when it is reversed or turnedlower side uppermost. Of course it will be understood that in reversingthe wipers the plates are not only turned lower side upward but the lefthand plate is replaced in the right hand wiper holder as indicated indotted lines in Fig. 3 to adapt the edge contour presented by the platesto the edge contour of the last which is mate to the one indicated infull lines.

Having explained the nature of this invention described a preferredconstruction embodying the same, I claim as new and desire to secure by.Letters Patent of the United States 1.
